Unless you are stuck with framework 1, don't use ArrayList at all.
Use a generic list. As it's strongly typed you don't need any casting:
List<Bookinfo> a = new List<Bookinfo>();<br />
Bookinfo b = new Bookinfo();<br />
a.Add(b);<br />
return a.ToArray();
Despite everything, the person most likely to be fooling you next is yourself.

Dim dtDate(table.Rows.Count) as DateTime
Dim iValue(table.Rows.Count) as Integer
For row as Integer = 0 To table.Rows.Count
dtDate(row) = table.Rows(row).Item("DateColumn")
iValue(row) = table.Rows(row).Item("ValueColumn")
Next
Basically you keep recreating your arrays within the For..Next code block.

This is a great suggestion, and similar to what I was doing.
The down side is that this array needs to be used by a different procedure and once I have gone out of scope in the dataset procedure the Arrays are empty when I get to the procedure they are to be used in.

Dim objStreamWriter2 As StreamWriter
Dim DTString As String
DTString = "C:\ETCLINK\" + Convert.ToString(Date.Now)
'Pass the file path and the file name to the StreamWriter constructor.
objStreamWriter2 = New StreamWriter(DTString)
I take a runtime error when the code is run. What is the problem? Thank you?
(objStreamWriter2 = New StreamWriter("C:\ETCLINK\09042008121212.txt") no problem here

Hmm.
Check out "DTString". When run it could be set to:
C:\ETCLINK\2001-01-01 11:11
This isnt a valid filename... The colon symbol ( : ) is a bad char.

I would concur with the other reply, although if you actually gave us the error message, we could provide a better answer.
If the problem is the resulting string from Date.Now, use the Format command to get the resulting string into the desired format.

The best solution ofcourse is to adapt your query (SELECT ISNULL(YourTable.YourField, 0) etc). If you can not adapt the query, another solution is to use IsDbNull(Datarow.Item("YourField"))
If IsDbNull(Datarow.Item("YourField")) Then
Textbox.Text = ""
Else
Textbox.Text = Datarow.Item("YourField")
End If
Hope it helps,
Johan

I’m glad to hear that, you’re welcome 
I’d like to point out that you should always reply to the original post instead of creating a new thread for the following reasons:
1- The new thread will take space in the message board and people would think it’s a question or something important.
2- If you create a new thread instead of replying, the original post’s author will not get notified by email that you posted something. I would have missed your reply if I had not checked the forum.
3- Even if the original post’s author notices your post, he/she may get confused what this post is for.

You can't do it with HTTP its the wrong protocol (HyperText Transfer Protocol). You need to use FTP (File Transfer Protocol). The clue is in the names of the protocols.
